Zimmer and she died Apr 23, 1977 in Seattle, WA.At the time of her fathers death in 1937 she was married to Wayne Davis.The burial records for her mother indicate that in 1977 she is Frances Wilson.Her mother's obit indicates three grand children and five great grandchildren.I believe that Frances was probably born in the early 1900's.Any suggestions or help are welcome!!
